Detailed Documentation
This MATLAB-based program calculates laser power distributions in fiber lasers by solving the fundamental rate equations. The implementation employs numerical methods to compute both the laser field distribution and electron density distribution within the fiber laser cavity. Through these calculations, the program determines the lasing power density profile along the fiber length. Key algorithmic features include finite difference methods for solving differential equations and iterative convergence techniques for stable solutions. Additionally, the program provides comparative analysis capabilities for different laser parameters (such as pump power, fiber length, and doping concentration), enabling users to optimize laser design and performance through parameter studies. The code structure includes modular functions for equation definition, numerical solver implementation, and result visualization using MATLAB's plotting capabilities.
